MD series motors
High-performance motors for
use with SVA & SVAHX drives
Parker’s MD series servo motors provide exceptional
performance in relation to size and are a perfect match for the
SVA drive range. Currently available with NEMA 34 size
flanges and in two frame lengths, MD motors offer peak torques
up to 14Nm and maximum speeds up to 5000 rpm.
MD motors use neodymium-iron-boron magnets in a 6-pole
rotor design. An incremental encoder with a resolution of 1024
lines/rev (4096 counts/rev after decoding) provides feedback for
position control and commutation. A separate six-step encoder
is used for initial commutation at power-up.
Separate MS-style connectors are used for the motor and
encoder connections. Alternative shaft diameters provide
additional applications flexibility, the larger 19mm shaft being
recommended for toothed-belt applications where radial loads
are higher. The motors are EMC and LVD compliant and are
rated at IP54.
The SVA1200S drive may also be used in conjunction with the
SM233AE motor. For further details and dimension drawings of
the SM series motors, please see “SM, NeoMetric and J series
motors” later in this catalogue.

The 14mm shaft option is suitable for in-line coupling (e.g. leadscrew or gearbox) and for toothed belts up to 15mm wide.
For toothed belt transmissions utilising the full motor power, the 19mm shaft is recommended.

Continuous curves: (A) in free air, (F) flange-mounted.
Data relates to operation in 20°C ambient and 230V supply, single phase for SVA1200S, three phase for SVA2500S. Peak
torque knee speed will be reduced by approximately 15% for SVA2500S on single phase supply
Power dump curves are based on using the BRM05/01 dump with MD motors and no external dump with the SM233 motor
Power dump dissipation curves
In addition to torque-speed data, the performance graphs
give an indication of the safe operating area of the power
dump circuit in repetitive start-stop operation. The data is
based on a 'worst case' system performing repeated
trapezoidal moves with no dwell in between. The time at
maximum speed is as short as the thermal rating of the
motor will allow. Under these conditions, for any given load
inertia, the power in the ballast resistor depends on the
peak torque during deceleration and the maximum speed.
The broken lines represent different load inertias as a ratio
of the motor inertia Jm. When the application requirements
have been calculated, plot the point representing peak
torque and maximum speed on the performance graph. If
this point lies to the left of the corresponding inertia line, the
resistor rating will not be exceeded. If it lies to the right,
there is not necessarily a problem but further calculation is
required to establish the dump power more accurately -
please consult your supplier. For example, a peak torque
of 3Nm and a maximum speed of 2500rpm are acceptable
with the MD3450 motor and SVA1200S drive when driving
a load equal to 10 times the motor inertia.
Note that this information is for general guidance purposes
only and will not apply to applications in which the duty
cycle is light.
